Embrace the Power of Nature,
Unlock the Science of Beauty.

Celebrating the pure beauty found in simplicity and naturalness, IREN Shizen is a French-Japanese vegan skincare brand that embraces the ancestral and spiritual skincare rituals of Japan while infusing them with the unique essence of the French way of life.

Thoughtfully designed to cater to the diverse needs of the skin while adapting to the modern lifestyle, our carefully curated collection of skincare essentials is created each with a specific function to target skin concerns effectively as they reveal the harmonious balance between tradition and innovation, where time-honored rituals meet scientific advancements.

Finding the perfect balance between efficacy and gentleness is the modern beauty's biggest challenge. The use of highly-concentrated active ingredients can sometimes lead to discomfort or irritation, whereas insufficient use of these ingredients may not produce the desired results.

We understand the importance of preserving your skin's delicate balance while achieving the desired results. Our patented Encapsulated Biyusen™ technology ensures that active ingredients penetrate 10 times deeper and faster into the skin's layers. The time-release effect of the encapsulation allows for the usage of highly concentrated active ingredients without sensitizing the skin.

Harnessing the power of our encapsulation technology, our powerful blend of highly concentrated active ingredients is perfectly balanced to deliver the safest and most effective results for the skin. We take pride in using only the highest quality ingredients, sustainably sourced from Japan with a natural origin of up to 95%-100%.

At the heart of all formulations lies our exceptional BIYUSEN™ complex derived from Moor Onsen Water – a precious Japanese hot spring water sourced from the serene island of Hokkaido – creating the ultimate efficacious skincare that offers gentle yet transformative benefits for your skin.

As we believe that beauty is a journey, and each person's path is unique, we aim to empower individuals to nurture their natural beauty and cultivate their own sense of well-being by embracing simplicity and finding joy in the little moments of self-care. 

Inspired by the Japanese art of layering, our products are made to be incorporated into your daily beauty routine to encourage mindfulness and self-love with a minimalistic approach, as they invite you to reconnect with yourself.

Rooted in the belief that true beauty should be nurtured by nature itself, our commitment to sustainability goes beyond our ingredients and production methods as we strive to build strong relationships with our producers, fostering fair trade practices, supporting local communities, and manufacturing in small batches to avoid skincare waste.

As we uphold the principles of meticulous craftsmanship and attention to the environment, we prioritize working with individuals who share our vision of sustainable development, harmoniously aligned with nature's rhythm and constraints.
